Opener will not run; lights flash nine times; remotes and wall control may appear to work but motor does not move.

Safety first: Unplug the opener. Static discharge can damage electronics; ground yourself before handling the board. If you are not comfortable with electronic repairs, contact a professional.

• Visual inspection: Remove the opener cover and inspect the logic board. Look for burn marks, swollen components, or corrosion around connectors.
• Check power input: Verify the outlet has proper voltage using a meter. Confirm the opener's power cord and internal fuse (if present) are intact.
• Inspect connectors: Reseat all harness connectors to the logic board, including motor, sensors, and wall control. Loose connections can mimic board failure.
• Surge protection: If the failure followed a storm or power surge, install a surge protector on the opener circuit after repair.
• Replace logic board: If the 9-flash code persists and other components test good, replace the logic board with the exact Craftsman part number. Transfer each connector one at a time to avoid miswiring.
• Reprogram remotes: After installing a new board, reprogram all Craftsman remotes and keypads per the manual.
